in the title keeps popping up, even though (self.frame_left_menu) definitely exists.
i wish to obtain the width of the frame(frame_left_menu) when the toggle button is clicked.
Please enlighten me on what I am doing wrong and/or a workaround to get the same result
The code has been converted from .ui file to .py file via pyuic6 command and I have installed PyQt6 already.the exact error is :-
Traceback (most recent call last): File "D:\Python\Pyhton\PyQT\project\ui_main.py", line 216, in <module> ui.setupUi(MainWindow) File "D:\Python\Pyhton\PyQT\project\ui_main.py", line 73, in setupUi self.btn_toggle.clicked.connect(self.toggle_clicked(140, True)) File "D:\Python\Pyhton\PyQT\project\ui_main.py", line 192, in toggle_clicked wid = self.frame_left_menu.width() AttributeError: 'Ui_MainWindow' object has no attribute 'frame_left_menu' -
Hi and welcome to devnet,
Your connect statement is wrong.
self.btn_toggle.clicked.connect(self.toggle_clicked(140, True))
What happens is that you connect the signal to the value returned by the call to toggle_clicked. Since you are calling it now, the rest of the widgets have not yet been created and thus the error you are getting.
-
No it won't.
Here is this line rewritten for clarity about the sequence of events:
result = self.toggle_clicked(140, True) self.btn_toggle.clicked.connect(result)If you want to pass variables like that to the slot when clicking the button, either use a lambda as the connect target or an intermediate parameter less slot that will call
toggle_clickedwith the parameters you want. -
alright, i think i understand
but i do not quite understand what you mean by "use a lambda as the connect target"
from what i found online, it seems to be something of this sortself.btn_toggle.clicked.connect(lambda: self.toggle_clicked(140, True))and if this is what i am supposed to do, it just in turn gives me this error when i click the toggle button:
Process finished with exit code -1073740791 (0xC0000409)it just seems to be an error suppression
if i am understanding this completely wrong, please help me out
thanks and regards -
@Flare said in AttributeError: 'Ui_MainWindow' object has no attribute 'frame_left_menu':
self.btn_toggle.clicked.connect(lambda: self.toggle_clicked(140, True))
Should be
self.btn_toggle.clicked.connect(lambda self: self.toggle_clicked(140, True)) -
@jsulm
i still get the same errorProcess finished with exit code -1073740791 (0xC0000409)is there perhaps something wrong within my function? i get all other input within the function just fine before reaching the
wid = self.frame_left_menu.width()line
thanks and regards -
What does the debugger tell you when you hit that line ?
